Functions
constexpr bool	comm::nccl_available ()
	Whether this build can exchange device buffers with NCCL.

void	comm::enqueue_wait (const Kokkos::DefaultExecutionSpace &waiter, const Kokkos::DefaultExecutionSpace &done)
	Make the work enqueued later on waiter wait for the work enqueued so far on done, without blocking the host where the backend allows it (CUDA); a fence of done otherwise.
